I agree with Chris wholeheartedly about "sticking to the path." I was 60 pounds overweight and very sick. Had a liver condition that was killing me and suffered from deep depression. I am a writer by trade, and I could ot even write my own name at times. Would spend most of my days alone in my apartment with the phone turned off so nobody would bother me. It was horrible.
I came across fasting in desperation. I tried not to eat for one day and got really ill. The withdrawal was so bad I almost passed out. I went out and ate a cheeseburger and the symptoms all but disappeared. This really intrigued me. Soon I realized how my toxic insides were actually causing these withdrawals. For me it was crucial to walk through the withdrawal and come out the other side. I am so glad I did. Like Chris, I have more energy and vitality today than I did when I was 20. And I just turned 41!
We have to stick together though. Do not give up. Hang in there. After seven to 11 days, the symptoms all but vanish. I recall feeling I could go on fasting indefinately. This is the miracle zone. May it happen for you. Best regards and let us know if we can be of further service and/or support.
